A revolutionary app that helps reduce air conditioner use and maximizes the benefits of using whole house fans.

About Cool Off

Cool Off is a revolutionary app that automatically notifies you when the weather outside is cool enough to turn off your air conditioner and start using greener methods to cool your home, like opening windows and turning on whole house fans. Before Cool Off, reducing A/C use meant having to lower your standards on comfort by enduring warmer weather, waiting until the evening to turn off your A/C, or having to constantly check the weather outside to know the right time to use greener methods to cool your home. Not only does Cool Off take away all the guess work for you, Cool Off makes it virtually effortless and financially beneficial to becoming environmentally friendly. The ability to customize your settings means not having to compromise on comfort.
